«One little known feature in Haiku is the ability to run apps on a remote system, similar to rdesktop for windows or the more common VNC. Unlike VNC (which is also available), the remote app server forwards app_server calls through the network and let the drawing happen on the client side (where the screen is). This is actually quite similar to X forwarding on unix systems.»
Правда
«The RemoteDesktop is a fullscreen window, there is no „rootless“ mode. You can, however, have local windows shown above it.»
